Few reports have described successful lung transplantation from a donor with a history of SARS-CoV-2 infection, and outcomes beyond 3 to 6 months remain unknown. After weighing the urgency and life-saving benefits of lung transplantation against the risk of viral transmission, we successfully performed a bilateral lung transplant from a donor with confirmed SARS-CoV-2 infection with mild symptoms 2 months before donation. At 1 year after transplant, there is no evidence of donor-derived viral transmission, and allograft function is excellent and stable, with FVC of 3.66 L (77% predicted) and FEV1 of 3.08 L (85% predicted). With careful selection, lung transplantation from a donor with a history of mild SARS-CoV-2 infection was performed safely, with good allograft survival.


SARS-CoV-2; COVID-19; lung transplantation 

1. Introduction

It has been over 2 years since the emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its resulting respiratory illness, coronavirus disease 2019 (COVID-19). As of October 2022, over 600 million cases of COVID-19 have been confirmed globally by the World Health Organization [1]. The impact of the ongoing pandemic on organ transplantation has been profound, affecting the management of organ donors, potential candidates, transplant recipients, and clinical teams around the world. Despite an increasing volume of research on COVID-19, questions surrounding its effect on lung transplantation (LTx) remain, including how to balance the risk of donor-derived viral transmission with a limited donor pool, particularly one with an increasing proportion of potential organ donors previously infected with COVID-19. Because the respiratory tract is the primary reservoir for SARS-CoV-2, lung donation from a previously infected donor carries a unique concern. A previous report unfortunately confirmed viral transmission from lung donor to recipient [2]. Although the consensus remains that a history of SARS-CoV-2 infection should not preclude lung donation, it is unclear if the prior infection will affect the quality of the lung allograft and outcomes after transplantation. Successful bilateral LTx from donors previously infected with SARS-CoV-2 has been reported [3,4], but outcomes beyond 3 to 6 months are unknown. Herein, we report stable allograft function 1 year after bilateral LTx from a donor who recovered from COVID-19 with mild symptoms. To our knowledge, this case reports the longest post-LTx outcomes from a donor with previous SARS-CoV-2 infection in the United States.

2. Case Description

2.1 Recipient

A 63-year-old man with end-stage pulmonary fibrosis, without additional significant medical history, completed LTx evaluation at our center and was listed for bilateral LTx on August 6, 2020, with a lung allocation score of 65.1. Thirteen days after being activated on the list, the patient received a donor offer, with details below. Preoperatively, the recipient tested negative for SARS-CoV-2 by RT-PCR of a nasopharyngeal swab sample, and he denied any recent symptoms or exposure history.

2.2 Donor

The 28-year-old donor was declared brain dead after being injured in a motor vehicle accident. The donor had no significant past medical or smoking history. The family reported that 2 months prior, the donor had a SARS-CoV-2 infection confirmed by RT-PCR of a nasopharyngeal swab sample performed at a local urgent care center. The donor was reported to have been mildly symptomatic with ‘a few days’ of fever, gastrointestinal upset, and a non-productive cough lasting 2 weeks. Detailed retrospective assessment of disease severity was limited, but the disease course was seemingly mild given a reported lack of dyspnea. The donor family denied any known exposures within 14 days before donation.

As a part of the SARS-CoV-2 donor screening protocol utilized by the organ procurement organization, multiple upper and lower respiratory tract samples were collected from the donor. Two nasopharyngeal swab specimens were collected 24 hours apart, both with a negative RT-PCR result. A lower lobe bronchoalveolar lavage sample taken 48 hours before the lung donation offer was also negative for SARS-CoV-2. Bronchoscopy of the donor lungs did not reveal significant secretions or airway anomalies. A chest radiograph was negative for significant pulmonary infiltrates. Computed tomography of the chest revealed a lower lobe pulmonary embolus and bilateral pneumothoraces with chest tubes in place (Figure 1).

An arterial blood gas test on standard challenge settings of FiO2 of 1.0 and positive end-expiratory pressure of 5 cm H2O demonstrated a PaO2 of 417 mmHg (P/F ratio of 417). Based on these results, we considered the lungs acceptable for donation. Subsequently, the detection of SARS-CoV-2 IgG antibodies confirmed prior infection; serum SARS-CoV-2 IgM antibodies were not detected.

2.3 Decision

After extensive multidisciplinary discussions involving pulmonary medicine physicians, infectious disease experts, cardiothoracic surgeons, and transplant administrators, and per International Society for Heart and Lung Transplant criteria, the donor lungs were accepted for transplantation.

2.4 Transplant Course

Pretransplant recipient testing for COVID-19 via nasopharyngeal swab RT-PCR was negative. The donor lungs were deemed suitable for transplant during operative evaluation. The patient promptly underwent bilateral LTx without intraoperative complications. The early postoperative course was significant for grade 3 primary graft dysfunction and brief use of inhaled nitric oxide. The recipient was extubated on the second postoperative day on 2 liters of oxygen via nasal cannula. He was ambulating and transferred to telemetry on postoperative day 3. The retrospective cross-match analysis was negative. Induction therapy included basiliximab and methylprednisolone. He was started on our standard immunosuppressive protocol with tacrolimus, mycophenolate mofetil, and prednisone. He also received opportunistic infection prophylaxis with trimethoprim/sulfamethoxazole, itraconazole, valganciclovir, and inhaled amphotericin B, as per our center protocol. He experienced a relatively unremarkable postoperative course and was discharged to home on postoperative day 8.

2.5 Outcomes

A complete timeline of events, including SARS-CoV-2 testing, radiographic findings, pulmonary function testing, transbronchial biopsy results, and attempts to detect donor-specific antibodies with a mean fluorescence intensity threshold ≥2,000, is reported in Figure 2. Our patient has not required re-hospitalization since his initial discharge. He had 1 episode of known exposure to COVID-19 from an actively infected and symptomatic family member in December 2020; he did not develop symptoms, and 3 consecutive RT-PCR results were negative. He has completed a 2-shot COVID-19 vaccination series with booster immunization, without side effects. At 12 months after transplant, allograft function is excellent and stable, with FVC of 3.66 L (77% predicted) and FEV1 of 3.08 L (85% predicted).

3. Discussion

The COVID-19 pandemic has significantly exacerbated the shortage of donor organs. A descriptive study seeking to analyze the effects of the pandemic on LTx highlighted a 10% decrease in LTx volume in the United States, along with a significant reduction in donor availability, particularly in areas with moderate and high COVID-19 prevalence rates [5]. Thus, it is pertinent to ascertain whether those with a history of COVID-19 can be considered potential lung donors.

A few reports of adverse outcomes from donor-derived infections have prompted most regulatory agencies to issue guidelines to decline or defer organ donation from donors with a confirmed, recent SARS-CoV-2 infection [6]. Another study reported 2 possible lung donations that were not accepted based on donor PCR cycle thresholds of 44 and 39.8 and suspicious radiographic findings, suggesting that viral load assessment could play a role in donor selection for LTx [7].

Recommendations have been evolving as new evidence comes forth. The International Society of Heart and Lung Transplantation has outlined selection criteria for donor organs in the setting of previous SARS-CoV-2 infection or exposure. The document specifies that given a lack of effective, evidence-based treatment for COVID-19, the best practice is to avoid lung transplantation from a PCR-positive donor, particularly due to the potential for deleterious consequences of donor-to-recipient viral transmission. Their guidelines, revised in August 2020, emphasize that the donor should be more than 28 days from symptom onset and outline the requirements to ensure clinical, virologic, and radiographic resolution of prior SARS-CoV-2 infection before the donor organ is considered for transplant [8]. Effective May 2021, the Organ Procurement and Transplantation Network has also implemented a policy requiring negative SARS-CoV-2 nucleic acid test results of lower respiratory specimens (sputum, tracheal aspirate, bronchial suction, bronchial wash, bronchoalveolar lavage (BAL), or lung biopsy) before LTx [9].

Studies suggest that a notable majority of those with prior infections recover without long-term systemic effects, and solid organ transplants have been cautiously performed from donors with prior mild SARS-CoV-2 infection [10]. One center conducted 12 heart transplants and 2 bilateral lung transplants from 14 donors positive for SARS-CoV-2 by nasopharyngeal swab PCR [11]. Only donors with asymptomatic or past mild COVID-19 without hypercoagulable or hyperinflammatory states were considered. Of note, they had ensured that the donor’s lower respiratory tract specimens (2 consecutive BALs) were negative for SARS-CoV-2 prior to the 2 lung transplants. The authors concluded that heart transplants might be safe, but suggested exercising increased caution in LTx in view of SARS-CoV-2 transmission via respiratory secretions. However, the risk of long-term effects from COVID-19 on lung function remains pertinent [12]. Therefore, evidence addressing long-term allograft function after LTx from donors with prior mild COVID-19 is of great significance. Our case report describes LTx carried out per current recommendations and policies, and moreover illustrates good lung allograft function 1 year after bilateral LTx.

In the setting of an ongoing pandemic due to a virus that predominantly affects the lungs, a growing number of organ donors are bound to have a history of SARS-CoV-2 exposure or infection, either symptomatic or asymptomatic, potentially exacerbating the critical shortage of donor organs. The safety and feasibility of transplant of non-lung organs have been documented. Now, our community needs further documentation of long-term lung allograft outcomes after LTx from donors with previous mild SARS-CoV-2 infection, as shown by our case report, to better inform our decisions regarding this practice in LTx. It is therefore imperative to report these long-term posttransplant outcomes to contribute to the growing body of evidence that can help expand the donor pool and optimize donor selection in the COVID-19 era.

4. Conclusion

SARS-CoV-2 testing for our lung donor was performed in accordance with the evidence for best practices when protocols and consensus statements were not yet summarized by the United Network for Organ Sharing or the Organ Procurement and Transplantation Network. Here we report the longest posttransplant outcomes after bilateral LTx from a donor with a history of mild SARS-CoV-2 infection (confirmed with serological testing). This report demonstrates stable allograft function at 1 year after transplant, without significant levels of donor-specific antibodies or acute cellular rejection episodes.

Although a single case cannot definitively answer the complex questions regarding allograft survival in recipients of lungs from previously infected donors, this case adds to the mounting evidence of safety and feasibility. Collectively, our goal should be to strengthen our community’s understanding of the impact of prior SARS-CoV-2 infection in lung donors on LTx recipients, as it remains impractical to completely exclude such donors given the vast, global COVID-19 burden and ongoing supply-demand mismatch.
